We will create a new X-Pack folder, and move the x-pack-$PRODUCT code into that folder under the Elastic EULA allowing for some derivative works and contribution.

We will change the top-level license to a simple Elastic License that details that some files in the repo are Apache 2.0 and some are covered by an Elastic EULA.

Also, X-Pack features will now be bundled into the default distribution. All free features are included and enabled by default and will never ‘expire’, and commercial features are opt-in via a trial license. The license for free features never expires,you no longer need to register to use these capabilities. In addition to this, an Apache 2.0-only distribution will be created for download.

More information, and an FAQ, can be found on the Opening X-Pack page.
